This is a repost of my original file uploaded to PLINK on April 21, 1989.
I realized that there was a bit of information left out which made the
description of this file somewhat inaccurate in that I didn't really
mention the "performance" increases realized with a turbo-board.
Since I only own an '020 not an '030 board, I can only state reported
figures about performance. But, I have included Ronin's (written by John
Hinckly of RONIN and with their permission) CPU_SPEED test program which
graphically illustrates the overall CPU speed of your system. This is an
excellent utility for seeing just how much a task slows down your system
while running. This program is basically the SEIVE as stated in BYTE mag-
azine with the exception that a 256K instead of an 8K cache is used.
On a stock Amiga, running the CPU_SPEED test will show the CPU speed at
a value of 1. With a plain '020, that will change to 1.8-1.9. With a
plain '030, the speed picks up to about 2.01. Not much, considering the
expense. But add a math chip and you will get quite decent results in
heavy computational programs like Sculpt-3D.
Now, add 32-bit memory and this is where you start to pick it up a bit!
CBM's '020 board clocks at a best of 3.8-3.9 with it's memory. The Ronin
board clocks at 5.0. Now were talking much faster screens, DIR listings
and the like.
So drop in an '030 piggyback module and the rating goes to 6 on the
scale. Remember, now we have a 256 command cache verus a 20 command
cache on the '020. Plus, with the '030s built-in Memory Management Unit we
can now map the KickStart Routines to 32-bit memory. This means MUCH
faster sytem operation. Having never seen one operating, I can only
speculate...
Up to now, we're still running at 14 MHz. What happens to the rating by
going to the new 25-28 MHz boards?
The rating goes off the scale to somewhere in the neighborhood of 12-15.
Makes you kinda drool, doesn't it????????
The rest of the file is the same as was posted earlier. Start saving your
coins!!!

THE FOLLOWING IS A TEXT FILE COMPARING THE PRICE AND PERFORMANCE OF THE
RONIN 68030 BOARD VRS THE GREAT VALLEY 68030 BOARD.
*************************************************************************
The following information was given to me by personnel at Ronin and GVP.
I am posting this information so as to better inform Amiga users
concerning expansion products for their AMIGAS. For the record, I own
the Ronin '020 Hurricane board and 32-bit 4-meg RAM board and the GVP SCSI
controller with 2-meg on-board RAM.
Both companies offer excellent products. The only discouragement with
the Ronin board is an inherent (due to the board design) problem with DMA
contention (manifested by slow harddrive throughput) when using such DMA
products as Commodore's 2090A harddrive controller. However, this same
design does make the Ronin board the fastest of the turbo-boards, and the
problem disappears if a non-DMA controller such as GVP's or Cltd' is used.
The GVP controller I bought from GO-AMIGO did have a problem with a very
tight fit in my A-2000 slots, the green wave solder insulation peeling
from the back, and the DB-25 connector at the rear of the controller being
incorrectly positioned to the edge of the cut-out so that the harddrive
connector couldn't mate all the way down onto the GVP connector. GVP is
exchanging the board with no hassle and with apology.

***************************************************************************
Obviously, the total bottom line for either board can be greatly influenced
by differing the speed of the '030, the type of math chip used, and by
starting out with a lesser amount of RAM. You will need at least two megs of
32-bit RAM when using an '030 as the KickStart routines are re-mapped to
this fast memory, which then REALLY starts speeding up the entire system.
You could get a Ronin board running an '030 at 28 MHz with 20 MHz 68882
math chip, and 2-megs of 32-bit memory for about $3000.00 by buying your
own RAM chips. For another $500.00 (list), however, you can get the GVP
board with another 2 megs of RAM.
Remember, the "bottom line" quoted above is List Price. User end price
should be quite a bit less, especially if you don't mind shopping around
for your own chips!
---------------------------------------------------------------------------
Does having a turbo-board make that much differnce? In a word,
YOU BET IT DOES!
Why do you think the MS-DOS world is all going ga-gah over the 386 CPU?
You have to experience the difference a turbo-board makes in multi-tasking.
Once you've turbo'ed, you'll never go back, why, I even TYPE faster now!
Hope you've found this information useful. Please feel free to comment on
